近期Baker Hughes公司开发了用于成熟油田的老油井稳产、增产的“近井筒区域污染的化学品修复(CND)”工艺。在油气井的生命周期中,各种化学阻塞物,例如石蜡、沥青、无机垢和乳液会在地层的近井筒区域积累,对油气井储层造成伤害,从而限制流体与气体顺畅流动,导致油气井产量降低或生产(举升)成本增加。Baker Hughes公司研制系列用于修复近井筒区域污染(CND)的化学产品,特别是通过一种耗时短的 Recently, Baker Hughes Company has developed a steady and increased production of old wells for oilfields in mature oilfields, a chemical recovery (CND) process near the wellbore area. During the life of the well, various chemical blockages, such as paraffin, bitumen, inorganic scale, and emulsion accumulate in the near-wellbores of the formation, damaging the well of the well, limiting the smooth flow of fluids and gases, Well production is reduced or production (lifting) costs are increased. Baker Hughes develops a range of chemicals for repairing near-wellbore contamination (CND), particularly through a time-consuming
